The present disclosure relates to remote controlling hardware using a remote and a computing device in communication with the remote, and more particularly to remote vehicle systems configured to be remotely controlled by a smartphone.
Remote vehicle starting and locking systems, keyless go systems and keyless start systems may be remotely controlled by a smartphone running an application program that is adapted to the remote vehicle system, provided that the smartphone is in range of the remote vehicle system such that a short-range wireless connection (e.g. Bluetooth connection) is established between the smartphone and the remote of the remote vehicle system.
However, with current remote vehicle systems and corresponding application programs running on a smartphone, the connection (i.e. pairing) between the smartphone and the remote of the remote vehicle system only occurs once the user provides input to cause the remote vehicle system to perform an action (e.g. start the vehicle, unlock the doors of the vehicle, etc.) or to run the corresponding application program on the smartphone. However, before the command can be issued, a short-range wireless connection has to be established between the remote and the smartphone. This causes unnecessary delay for the user (e.g. over ten seconds), who waits until the connection is established before the command is sent to the remote, actuating the remote vehicle system.
Therefore, it would be advantageous to have a remote vehicle system having a smartphone and a remote adapted to communicate with one another, such that an action could be performed by the vehicle following the receipt of user input provided to the smartphone, without having to wait for a short-range wireless connection to be established between the smartphone and the remote.
The present disclosure relates to an improved system for remotely actuating a hardware component (e.g. a remote vehicle system) that is configured to establish a short-range wireless connection between the smartphone and the remote adapted to control the hardware component, upon the smartphone coming into range of the remote. As such, because the short-range wireless connection is already established between the vehicle and the computing device, the commands inputted can be transmitted to the remote adapted to control the hardware component without the user having to wait until the short-range wireless connection is established between the computing device and the remote.
The application program stored in the memory of the computing device can cause a filter to be applied by the operating system that identifies identity sequences received by the receiver of the computing device that correspond to the remote.
Moreover, because the background application process of the computing device establishes a short-range wireless connection with the hardware component that is maintained for when the user would like to control the hardware component, or to receive notifications from the hardware component, this reduces the need of having a hardware component with an increased advertising rate (e.g. frequency of pings or identity sequences advertised) to establish rapidly a wireless connection when the computing device is in range of the hardware component. As such, as the advertising rate of the hardware component is reduced, this may also decrease the power consumption of the hardware component or its remote, while still establishing a usable short-range wireless connection between the computing device and the hardware component when the computing device is in a sufficient range of the hardware component to establish a short-range wireless connection.

The invention will be better understood by way of the following detailed description of embodiments of the invention with reference to the appended drawings, in which:
The present disclosure makes reference to a system for remotely actuating a remote vehicle system, such as a remote vehicle starter system, a keyless go system, a keyless start system, etc. (where the remote may be an original equipment manufacturer key, after-market key, etc.). However, it will be understood that the present disclosure may apply to other systems for remotely actuating a hardware component, such as remotely controlling a camera (e.g. a doorbell camera), a garage door, a thermostat, etc., where the hardware component is actuated directly or indirectly by a remote, the remote adapted to enter into communication with a computing device (e.g. smartphone) when the remote is in range of the computing device.
In the present disclosure, a “computing device”, may be a smartphone, desktop computer, a tablet computer, a smartwatch, a laptop, etc.
Reference is now made to
The hardware component 250 can be actuated by a remote 200. The remote 200 can be integrated to the hardware component 250, or can be separate from the hardware component 250 (when integrated, the remote 200—hardware component 250—may or may not have a transceiver 202 and/or an antenna 270).
A computing device 100 is adapted to enter into communication with the remote 200 when the computing device 100 is in range of the remote 200. A short-range wireless connection (e.g. Bluetooth connection, such as a BLE connection) is established between the computing device 100 and the remote 200 when the remote 200 is in range of the computing device 100, establishing a communication channel between the remote 200 and the computing device 100.
The computing device 100 has a processor 102 (e.g. a central processing unit), a memory 104 for storing instructions and program code executable by the processor 102, a short-range wireless transceiver 101 (or a short-range wireless receiver and a short-range wireless transmitter). The computing device 100 may have a display 103 and a wireless interface 105 for, e.g., establishing a long-range wireless connection (e.g. over the Internet).
The remote 200 may have a processor 204 (e.g. a microprocessor), memory 203 for storing instructions (e.g. program code) that are executable by the processor 204, a power supply 205 (e.g. a battery, a connection with an external power source, etc.) and a short-range wireless transceiver 201 (or a short-range wireless receiver and a short-range wireless transmitter) for establishing a short-range wireless connection with the smartphone 100. In some embodiments, the remote 200 may also have a wireless transceiver 201 (or a wireless receiver and wireless transmitter) for establishing a wireless connection with the hardware component 250 (or the antenna 270 as shown in
The hardware component 250 may cause another hardware component to perform an action. For instance, the hardware component 250 may be a remote starting unit installed in a vehicle for causing the vehicle to start upon the hardware component 250 being actuated directly or indirectly by the remote 200.
Reference is now made to
The computing device 100 has an operating system 106 stored as program code in memory 104, and executable by the processor 102.
The computing device 100 also has an application program 120 stored in memory 104 of the computing device 100. The application program 120 may provide an application interface that can run in the foreground to allow a user to provide input for remotely controlling the hardware component 250 using the computing device 100.
The application program 120 may also include instructions, stored in memory 104, that when executed by the processor 102 (and, e.g., after the computing device 100 is restarted or the application program 120 is run in the foreground) that causes the processor to generate a filter that causes the O.S. 106 to identify specific identity sequences issued by the remote 200 and received by the transceiver 101, thereby filtering out other identity sequences received by the transceiver 101. The filtered identity sequence is then transmitted by the O.S. 106 to the background process 107.
A background process 107 (running behind the scenes without user intervention) is also stored in memory 104 of the computing device 100 that is related to the remote 200 and/or the hardware component 250. The background process 107 may be part of the application program 120, or may be a standalone process or an application program. In some examples, the background process 107 may be associated with a service running on the computing device 100 for establishing a short-range wireless connection with a nearby device (e.g. a Bluetooth connection).
The background process 107 includes program code stored in memory 104 that is executable by the processor 102 to receive an identity sequence generated by the remote 200, captured by the transceiver 101, and transmitted by the O.S. 106. Upon receipt of the identity sequence, the background process 107 may verify the identity of the remote 200. The background process 107 may include instructions stored in memory 104 that, when executed by the processor 102, (e.g. following verification of the remote 200) cause the generation of a connection sequence (e.g. a challenge) that may be transmitted to the remote 200 (via the O.S. 106) using the transceiver 101 (or a transmitter). The challenge may be one as is known in the art for establishing a connection (e.g. initiating a handshake) between a smartphone and a remote.
In some embodiments, a receiver antenna 270 may also be installed in the vehicle 280. The receiver antenna 270 is configured to receive a command signal from the transceiver 202 for actuating the remote vehicle starter unit 250. As such, the receiver antenna 270 may be paired with the transceiver 202. The receiver antenna 270 may be a short-range receiver or a long-range receiver. The connection between the receiver antenna 270 and the remote vehicle starter unit 250 may be a wired connection.
In some embodiments, the computing device 100 may be in communication with a hardware component 250 that does not have a remote 200. Reference is made to
An exemplary stereo system 250 may have a processor 204a, memory 203a, a power source 205a (e.g. battery; connection to power outlet) and a speaker 251. The stereo system 250 also has a transceiver 201a for establishing a short-range wireless connection with the computing device 100.
The short-range connection between the stereo system 250 and the computing device 100 is established in accordance with the present teachings when the computing device 100 comes into range with the stereo system 250.
Once the short-range wireless connection is established between the stereo system 250 and computing device 100, the user may use the application program 120 to send instructions to the stereo system 250 for controlling the stereo system 250 (e.g. play a given radio station; stream music to the stereo system 250; adjusting volume of the stereo system 250, etc.)
Moreover, the stereo system 250 may also send notifications, via the short-range wireless connection, to the computing device 100. The notifications are received by the background process 107. The background process 107 receives the notification messages and transmits the notification messages to the operating system 106 for display by the operating system 106 on the display of the computing device 100. Such notifications may include, e.g., that the battery of the stereo system 250 is low, that a new musical genre is playing, the track name, etc.
Reference is now made to
The application program 120 includes program code stored in memory 104 that, when executed by the processor 102, causes the O.S. 106 and the transceiver 101 to listen for identity sequences specifically generated by the remote 200 at step 305. For instance, the application program 120 may generate a filter for identifying identity sequences generated by the remote 200 (that may be set after the application program 120 is run, or when the computing device 100 is restarted, or turned on and off).
The transceiver 101 may receive the identity sequence of the remote 200, e.g., broadcast over a publicly known channel (e.g. a BLE channel) at step 310.
The O.S. 106 and the transceiver 101, adapted to listen for the identity sequence of the remote 200, may verify the identity sequence of the remote 200 at step 315.
If the identity sequence is not that of the remote 200, at step 320, this is indicative of the remote 200 not being in range at step 325. The O.S. 106 (and the transceiver 101) may then continue to listen for an identity sequence generated by the remote 200 at step 315.
If the identity sequence is identified as being generated by the remote 200 at step 330, the identity sequence is transmitted to the background process 107 at step 335.
After receiving the identity sequence (in some examples, the background process 107 may verify the identity sequence received from the remote 200), the background process 107 generates a connection sequence (e.g. a challenge for establishing a handshake with the remote 200) at step 340 for causing a short-range wireless connection to be established between the computing device 100 and the remote 200. The connection sequence is one as is known in the art for establishing a handshake with the remote 200, where, e.g., the remote accepts the user ID of the logged user.
The connection sequence is transmitted to the remote, via the O.S. 106, using the transceiver 101, now that the computing device 100 is in range of the remote 200, over the short-range wireless connection.
Upon completion of the challenge, a short-range wireless connection is established between the computing device 100 and the remote 200 at step 345. This short-range wireless connection may be maintained provided that the computing device 100 and the remote 200 remain in range.
The background process 107 may remain dormant as the short-range wireless connection has been established at step 350.
The short-range wireless connection is therefore established between the computing device 100 and the remote 200, such that, when the user provides input using the application interface 108 of the application program 120, the user does not have to wait for the short-range wireless connection to be established prior to sending out the command signal or data to the remote 200 for causing the actuation of the hardware component 250.
In some embodiments, the computing device 100 may initiate periodic handshaking with the remote 200 to maintain the short-range wireless connection with the remote 200.
Reference is now made to
The remote 200 may be configured (have program code stored in memory of the remote and when executed by the processor of the remote) to periodically generate and broadcast an identity sequence over the short-range wireless transceiver 201 (or transmitter) at step 410.
In some examples, the remote 200 may verify, or act depending on the receipt of a connection sequence from the computing device 100 generated by the computing device 100 after the computing device 100 received the identity sequence broadcast by the remote 200 at step 440.
If the remote 200 did not receive a connection sequence from the computing device 100 at step 420, the remote 200 continues to periodically generate and broadcast the identity sequence at step 410.
However, if the remote 200 did receive a connection sequence (e.g. challenge) from the computing device 100 at step 430, the remote 200 may carry out the challenge and establish the short-range wireless connection with the computing device 100 at step 450, and may stop generating and broadcasting the identity sequence.
The remote 200 may then wait at step 460 until the remote 200 receives a command signal or command data from the computing device 100 (e.g. smartphone) transmitted over the short-range wireless connection for causing the actuation of the hardware component 250 via the remote 200.
It will be understood that if the short-range wireless connection (e.g. the paired connection) between the computing device 100 and the remote 200 is lost (e.g. because the computing device 100 and the remote 200 are out of range), then the remote 200 may begin again generating and broadcasting identity sequences, as described in step 410.
In some examples, the remote 200, separate or integrated to the remote starter unit 250, may be configured to, once the wireless connection is established between the remote 200 and the computing device 100, generate messages or notifications sent over the wireless connection to the transceiver 101 of the computing device 100. The messages may, for instance, provide information as to the status or condition of the vehicle, such as, for instance, that the vehicle has reached a given temperature, that the vehicle is on/off, that the front lights of the vehicle are on, that a door of the vehicle is unlocked, that the trunk of the vehicle is open, etc. The message may also be a notification that the vehicle is in range with a user who has possession of the computing device 100.
In some examples, the remote starter unit 250, the remote 200, may include additional sensors to detect certain changes in the properties of the vehicle 280 (e.g. a temperature sensor for detecting the temperature of the vehicle 280, a proximity sensor to detect if a door is open, etc.) In other embodiments, the remote starter 250, or the remote 200, may be connected or may receive information from components of the vehicle 280 (e.g. temperature sensor) that can detect a change in the property of the vehicle 280.
In some embodiments, the message may be transmitted via the antenna 270 to transceiver 202. In turn, transceiver 201 may transmit the message to the transceiver 101 of the computing device 100.
In other embodiments where the remote 200 is part of the remote starter unit 250, the message may be transmitted directly from the transceiver 201 to the transceiver 101 of the computing device 100.
Upon receipt of the message by the transceiver 101, the message is transmitted to the background process or service 107 (e.g. of short-range wireless connection service (e.g. Bluetooth service) or of the application program 120). The background process 107 receives the message and instructs the operating system 106 of the computing device 100 to generate a notification on the display of the computing device 100 corresponding to the message.
For instance, if the message received by the background process 107 is indicative of the vehicle 280 reaching a given temperature, then the notification, appearing on the display of the computing device 100, may be “Vehicle at 20° C.”. It will be understood that other notifications may appear on the display of the computing device 100 in accordance with the message received from the background process 107 without departing from the present teachings.
Reference is now made to
Optionally, when a receiver antenna 270 is provided that is connected or connectable to the remote starter unit 250, the antenna 270 may be paired with the remote 200 at step 510.
The computing device 100 may also be initially paired with the remote 200 at step 520.
When a user runs the application program 120 on the computing device 100, the user's identity or credentials may be authenticated through a server at step 530.
A short-range wireless connection is then established between the remote and the computing device 100 as described herein at step 540, such that command signals/command data can be transmitted from the computing device 100 to the remote 200.
The computing device 100 can then receive command input from a user at step 550, that can be provided on an application interface 108, that results in the generation of command signals/command data that are sent over the short-range wireless connection to the remote 200 for causing the actuation of the hardware component 250.
